DNS Tutorial

file “slave/192.192.192.reverse”;

masters {kshounish1.bigleap.com}

};

If we go by dnsconf, it will create a slave under /var/named and then it will keep the files under it.

After we have done this just start the daemon

#/etc/rc.d/init.d/named restart (in kshounish2.bigleap.com.)

Similarly, for slave’s slave configuration, we can simply make another slave as kshounish4.bigleap.com saying that its master will be kshounish2.bigleap.com.

Remember

Whenever you do a new entry in zone file or reverse zone file of the master, always add 1 to the serial number and the restart daemon #/etc/rc.d/init.d/named restart.

But there is no need to restart the slave daemon.

Example:

Lets take the previous master file and updated master file and see the change in it
